Was out flying today with some friends. The rubber stopper came out of the gas tank - must have been because the plastic on the tank changed in size from the temperature (it was -3 here in Regina).

Anyway...I've got a mess. Most of the wood was fuel proofed. My question is the electronics. The receiver had fuel in it, as well as the battery connections and switch. The fuel I use is 100% synthetic.

I've got everything drying out at the moment. Are there any other precautions I should take with regards to the electronics? I guess I'm wondering about possible corrosion issues, or any other issues.

Thanks...Colin

What I have done when I got my Rx dunked (in the creek) is to remove the case and HOSE IT with 100% Iso-Propanol (Don't use "rubbing alchohol", as it usually has as much as 30% water in it). This will pick up any water, as in my case, but will also wash off the oil. Then let it air dry.

DO NOT try to hasten the process with a blow dryer or heat gun. The static electricity set up by the heated, moving air may cause damage to the electronics.

After it has air dried, reassemble it and test it.

Oil is a poor conductor of electricity so it should be ok as long as you clean it properly.

If it was me I'd never put those electronics in an airplane again.

At the very least check with the manufacturer, perhaps send them in for repairs or a checkout if you do the work. Too much at stake to chance it.

Most electrical suppliers that supply products to industry carry contact and circuit board cleaners in spray cans designed for this purpose. They will clean up the oil and moisture. These are inexpensive and work well. I also spray all my electrical equipment with a product called corrosion block. This is great stuff to keep moisture off the electrical componets.
Being a avid float flyer, most of my rc equipment is around water quite often and sometimes even decides to go swimming.

The major reason to get the oil off is to ensure it does not attack the plastic case. I expect castor should have no effect, as it is organic, but the synthetics might. If it is petroleum based oil it will soften the plastic.

....for all the good tips.
